FULVICIN P/G 330 vs VFEND
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fulvicin P/G 330 contains griseofulvin, which inhibits fungal cell mitosis by disrupting the microtubule function, binding to tubulin and preventing assembly of spindle fibers during metaphase.
Inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
330 mg orally once daily with fatty meal to enhance absorption.
IV: Loading dose of 6 mg/kg every 12 hours for 2 doses, then 4 mg/kg every 12 hours. Oral: Weight ≥40 kg: Loading dose of 400 mg every 12 hours for 2 doses, then 200 mg every 12 hours; weight <40 kg: Loading dose of 200 mg every 12 hours for 2 doses, then 100 mg every 12 hours.

Terminal half-life approximately 9-22 hours in adults, with a mean of ~13 hours. Clinical context: steady-state achieved in 2-3 days; may guide dosing interval.
Terminal half-life is approximately 24 hours (range 12–30 h) in adults. Prolonged in hepatic impairment (Child-Pugh A: 48 h; B: 72 h).
Primarily hepatic metabolism; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites: ~36% in feces, ~13% in urine.
Primarily hepatic metabolism; <2% excreted unchanged in urine. Fecal excretion accounts for ~80% of metabolites. Renal excretion of unchanged drug is negligible.
